The JBX42670 8-meter FC/APC to LC/UPC duplex singlemode fiber patch cable represents professional-grade optical connectivity engineered for demanding telecommunications and data center applications. This dual-strand duplex configuration enables bidirectional signal transmission, making it ideal for full-duplex communication requirements. **Technical Excellence** Constructed with a 9/125 singlemode fiber core and G.657.A1 glass fiber specifications, this cable delivers superior performance with insertion loss as low as 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB. These metrics ensure minimal signal degradation across long distances and high-frequency applications. The cable has been attenuation-tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing compliance with industry benchmarks. **Design & Durability** The bright yellow OFNR-rated (Optical Fiber, Nonconductive, Riser) jacket provides flame-resistant protection, making it suitable for installation in commercial building plenums and risers. The slim 1.8mm outside diameter facilitates routing through congested cable trays and conduits without compromising durability. RoHS/ELV compliant materials ensure environmental responsibility. **Connectivity & Compatibility** The FC/APC (Angled Physical Contact) to LC/UPC (Straight Physical Contact) configuration with Type A to B crossover polarity accommodates complex network topologies. This combination supports both legacy FC-based systems and modern LC-dominated installations. **Government & Enterprise Ready** TAA compliance certifies this cable for government contracting and procurement. The standardized packaging and available custom length options make procurement scalable for enterprise deployments. **Ordering & Support** Available in custom lengths to match your exact infrastructure needs.
